Understanding Throw Ratio
Throw ratio is one of the most important projector specifications.
It represents:
Throw Ratio = Distance from Projector to Screen ÷ Screen Width
For example:
- Throw Distance = 12 feet
- Screen Width = 8 feet
Throw Ratio:
12 ÷ 8 = 1.5
Lower throw ratios require less distance.
Higher throw ratios require more installation space.
Example Calculation
Suppose you have:
- Throw Ratio: 1.4
- Desired Screen Width: 100 inches
Calculation:
Throw Distance = 1.4 × 100
Throw Distance = 140 inches
The projector should be installed approximately 11.7 feet from the screen.
Our calculator performs these calculations instantly.
